The company announced Tuesday that it added broadband capacity for the campuses of Duke University, East Carolina University, North Carolina State University, the University of North Carolina Chapel Hill and the University of North Carolina Charlotte.

The company says it added the capacity to support some of its heaviest users and improve the performance of their devices.

AT&T’s North Carolina President Cynthia Marshall says the company realizes the importance of mobile broadband, especially for students who use tablets and netbooks in their classes.

The North Carolina improvements are part of the company’s plan to invest roughly $20 billion this year in its wireless and wireline networks.
